f CLZZ whom, i2 may concern:

Be itknown that I, GEORGE D. LAMM, a citizen of the United States, residing at Ackley, in the county of Hardin and State of Iowa, have invented a new and useful Straw Carrier and Stacker, of which the following is a specification.

The object of this invention is to provideimproved means for carrying strawfrom a threshing-machine and depositing the sameupon a stack, forstorin g the stacker mechanism upon the thresher for transportation, and for elevating the straw from the point of delivery at the thrasherinto the initial end of the stacker. My invention consists in the construction, arrangement, and combination of elements hereinafter set forth,pointed out in my claims, and illustrated by the accompanying drawings, in which Figure 1 is a side elevation illustrating my improved mechanism attached to the strawdelivery end of a threshing-machine in such a manner that the straw can be lifted from the elevator in the thresher to an elevated straw-carrier through the center of the turntable,upo11 which the straw carrier and stacker is carried, so that it may be vibrated, and also in such a manner that it can be rotated horizontally in reverse ways and extended in parallel position with the top of the thresher when the thresher is to be moved from one place to another. Fig. 2 is an elevation,

partlyin section, of a portion of my mechanism inclosed in a jacket through which the straw is elevated from the conveyer; that delivers straw and chaff from the riddles in the separator to the vibratory stacker. Fig. 3 is a side elevation of a portion of'my improved mechanism enlarged and taken from the side of the machine opposite to Fig. 1. Fig. 4 is a face elevation of one of the elevators detached from the machine. Figs. 5 and 6 are detail views relating to the turret mechanism.

In the construction of the apparatus and the mounting and driving thereof as shown the numeral 10 designates the straw-delivery end portion of a'threshing-machine to which my improved mechanism is attached. A jacket 11 and frame therefor are attached toand extend rearwardly from the thresher and contain or support all of the straw delivery, elevating, and stacking mechanism.

Shafts 12 13 are horizontally mounted in par allel planes and spaced apart a considerable distance within the jacket 11, and opposite ends of said shafts project from the jacket. A straw-co nveyer 14 is mounted for travel on sprocket-wheels fixed to the shafts 12 13 and receives the straw from the riddles of the thresher and delivers the same to the inte rior of the bottom of the jacket 11. A shaft 15 is mounted parallel with and adjacent to the shaft 13 transversely of the lower rear corner of the jacket 11 and projects at one end from said jacket. A belt-wheel 16 is mounted on the projecting end portion of the shaft -12and is connected to a belt-wheel 17 on the projecting end portion of the shaft 15 by abelt 18. A shaft 19 is mounted parallel with and above the shaft 13 transversely of the jacket 11 and projects from the jacket at one end. The projecting end portion of.the shaft 19 carries a belt-wheel 20, engaged at the lower portion of its periphery by the belt 18. A tightener 21 is mounted adjustably on the jacket-frame and engages the belt 18. The jacket 11 extends above the top of the threshercasing and is provided with a delivery-spout 22 at its rear end or margin. A shaft 23 is mounted transversely of the upper portion of the jacket 11 parallel with and directly above the shaft 15 and projects from the jacket at one end. Sprocket-wheels 2a 25 are mounted in pairs, Fig. 4, on the shafts 15 23, and conveyer-chains 26 27 are mounted for travel 011 said wheels. The chain 26 carriestubular slats 28, fixed thereto at one end and projecting at right angles therefrom toward the chain 27. The chain 27 carries solid slats 29, fixed thereto at one end and projecting at right angles therefrom toward the chain 26 and entering and telescoping within the slats 28 in order that the conveyor may be used in a space or chamber of less width at the top than at the bottom. A frame 30 is positioned vertically immediately above the shaft 15 and extends approximately two-thirds of the distance to the shaft 23. Grooves are formed in the faces of the frame 30 to receive the chains 26 27 and confine said chains in their travel. Guidebars 31 32 are mounted vertically in the jacket 11 at the opposite ends of the telescoping conveyer-slats on the chains 26 27 and are spaced farther apart at their lower ends than at their upper end. The conveyor-slats on the chains 26 27 abut at their extreme outer ends against the inner or adjacent faces of the guide-bars 31 32 and are guided thereby in telescoping. A bed or partition 83 is positioned vertically between the guide-bars 31 32 and extends downwardly from the shaft 23 nearly to the upper end of the frame 30. A shaft 34 is mounted transversely ofthe mouth or opening of the spout 22 parallel with the shaft 23 and projects from the spout at one end. Sprocketwheels 35 36 are fixed to the projecting ends of the shafts 23 34 and are connected by a sprocket-chain 37 outside the spout. A shaft 38 is mounted transversely of the spout 22, parallel with and a little distance below a plane common to the shafts 23 3t, and sprocketwheels 39 40, mounted in pairs on the shafts 3t 38, are connected by conveyer-ehains 41, having the ordinary conveyer-slats 42. A shaft 43 is mounted transversely of the upper portion of the jacket 11 and projects there from at one end. The shaft 43 is parallel with the shaft 23 and adjacent thereto and is located above the shaft 19 and nearer to the shaft than is the shaft 19 to the plane common to the shafts 15 23. Sprocket-wheels 4.4: 45 are fixed in pairs on the shafts 19 43 and are connected by conveyer-chains t6, one only of which is shown in Fig. 2. One of the chains 46 carries tubular slats t7, and the other of the chains t6 carries solid slats 48, entering and telescoping relative to the slats 4.7 in manner identical with the slats 28 29, hereinbefore described. A frame T9 is mounted between the shafts 19 t3 identical in construction with the frame 30, and guide-bars (not shown) also are provided at the extreme ends of the telescoping slats, corresponding with the guide-bars 31 A beater-shaft 50 is mounted transversely of the upper portion of the jacket 11 and projects therefrom at one end. The beater-shaft 50 is parallel with the shaft t3 and carries a heater 51, located within the jacket. The projecting end portion of the shaft 50 is provided with a sprocket-whcel 52, connected by a chain 5t to a sprocket-wheel 53, mounted on the projecting end portion of the shaft l3. Openings are formed in the opposite sides of the jacket 11, and doors 56 are hinged to the jacket and arranged to close said openings. A platform or step 57 is fixed to and projects horizontally from the jacket 11.

A bed 58 is fixed to and surrounds the jacketll in a horizontal plane near the top of the thresher, and a plurality of rollers 59 are mounted in recesses or a groove in the upper face of the bed and project slightly above the same, Fig. 5. A turn-table 60 of annular form is mounted horizontally on the bed 58 and is held against lateral movement by engagement with its inner surface of a plurality of antifrietion-rollers 61, mounted on studs seated in and projecting upwardly from the bed. The turn-table 6O rests upon the rollers 59 and revolves on a vertical axis. The

periphery of the turn-table 00 is rabbeted, and a gear-ring 62 is mounted for revolution in the rahbet and projects radially therefrom. That portion of the periphery of the turn-table 60 below the gear-ring 62 is provided with gear-teeth 03, Figs. 5 and 7, meshing with a worm (it on a worm-shaft 65. The wormshaft 65 is mounted for rotation in bearings 06 G0 on the bed 58 and is provided with a winch or hand-crank (37 at one end. The upper and lower sides of the ring 62 are provided with gear-teeth 68 09, respectively, and the teeth 69 mesh with a pinion 70, mounted rigidly on a short shaft 71, journaled for rotation in a bearing '72, fixed to the bed 58. The outer end of the short shaft 71 is provided with a sprocket-wheel 7 connected by a sprocketchain '74 to a sprocket-wheel '75 on the projectingend portion of the shaft 13. The teeth (38 of the gearring 62 mesh with a pinion 76, mounted for revolution on a stud 77, fixed to and projecting horizontally from the bracket 78. The pinion 7G meshes with a pinion 79, Fig. (5, mounted rigidly on a short shaft 80, journaled for rotation in the bracket 78 and an arm 81, fixed to said bracket. A sprocketwheel 82 is fixed to the onterend portion of the short shaft andis connected bya sprocketchain 8 to a sprocket-wheel St on the outer end portion of a shaft 85. By thus arranging the pinions 70 and 76 relative to the turntable 00, the gear-ring 62, and worm 64, that has a crank 67 on the end of its shaft 65, the stacker-frame 87 and operative mechanism carried thereby can be readily rotated horizontally, as required, to place the stackerframe over the thresher when the thresher is to be moved from one place to another. By this arrangement of parts it is obvious the stacker-frame and mechanism carried therebymy straw carrier and stackercan be permanently connected with a thresher andseparator and require no auxiliary support when in operation or when carried in an operative position. A bracket 86 is fixed to the turntable 00 diametrically opposite the bracket 78, and the bracket 78 also is fixed to the turn-table. The brackets 78 86 extend outwardly and upwardly from the turn-table (50 and are provided with seats or bearings in their extremities to support the shaft for rotation therein. A stackentrough 87 is pivotally mounted at its lower and inner end on the shaft 85, and the outer end of said trough carries a shaft 88. A conveyer 89 of common form is mounted on the shafts 85 S8 and travels longitudinally of the trough S7. The inner end portion of the trough 87 is beneath and overlaps the spout 22 when in operation. Standards 90 91 are vertically positioned-on opposite sides of the upper end of the jacket 11, and a drum 92 is mounted for rotation in the upper ends of the standards.

92 is provided with a ratchet-wheel 93, engaged by a gravity-operating pawl 94, pivoted on a stand 95, fixed to the top of the jacket 11, and a hand-crank 96 is fixed to one end The drum of the drum. Cables 98 are fixed to and arranged to be wound upon the drum 92 at their inner ends, and the outer ends of said cables are attached to the trough 87 near the outer end of said trough.

The stacker-trough may be adjusted to dif ferent inclinations by means of the cables winding upon or unwinding from the drum 92 and sustained in like manner at the desired angle to a horizontal plane. The stackertrough may be swung laterally in either direction, as desired by revolving the turn-table through the medium of the worm-gear operated by manual force applied to the crank 67. The turn-table revolves only when manually actuated, and the annular gear 62 serves simply as an intermediary to drive the chain 83 and stacker-conveyer.

The straw is delivered by the conveyer 14:, taken between the eonveyers vertically positioned in the jacket and deposited on the conveyer in the spout 22, and delivered by the latter conveyer on the conveyer 89 in the stacker-trough 87, by which it is carried to and placed upon the stack.

I claim as my invention 1. The combination of the delivery strawconveyer of a thresher, vertically-positioned eonveyers, of less width at their tops than at their bottoms and provided with telescoping slats, arranged to receive the straw therefrom and elevate the same, a discharging-conveyer arranged obliquely at. the upper ends of the vertical eonveyers and adapted to receive the straw therefrom and convey the same outwardly, an adjustable stacker, and a conveyer in the stacker arranged to receive the straw from the discharge-conveyer.
